代谢
利司扑兰的代谢主要由黄素单加氧酶1和3(FMO1和FMO3)介导,CYP1A1、CYP2J2、CYP3A4和CYP3A7也有所参与。母药大约占循环药物材料的83%。已确定一种药理学上不活跃的代谢物M1是主要的循环代谢物——这种M1代谢物在体外实验中被观察到能够抑制MATE1和MATE2-K转运体,类似于母药。
The metabolism of risdiplam is mediated primarily by flavin monooxygenases 1 and 3 (FMO1 and FMO3), with some involvement of CYP1A1, CYP2J2, CYP3A4, and CYP3A7. Parent drug comprises approximately 83% of circulating drug material. A pharmacologically-inactive metabolite, M1, has been identified as the major circulating metabolite - this M1 metabolite has been observed _in vitro_ to inhibit MATE1 and MATE2-K transporters, similar to the parent drug.
